To all whom "it may concern:

Be it known that I, JACOB Sonss, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Mechanical Lubricators, of whichthe following is a specification.

This invention relates to mechanical lubricators and is especiallyadapted for use on automobiles and other high speed machines.

The object of the invention is to provide a mechanical lubricator ofsimple construction and few parts in which the oil is delivered inquantities as required to a plurality of feeds by a single pump.

The invention has other objects in View which will appear hereinafter ina detailed description of the drawings which show one embodiment of theinvention and in which Figure 1 is a sectional elevation; Fig. 2 is asectional view on the line 22 of Fig. 1 Fig. 3 is a detail sectionalview Figs. 4 and 5 are sectional views on the line 44 of Fig. 1; Fig. 6is a detail sectional view.

Referring to the drawings in which like numerals of reference designatecorresponding parts in the several figures, 7 is an oil reservoir ofsuitable size and sha e within which the pump mechanism is inc osed. Adrive shaft 8 is j ournaled in a wall 7 of the reservoir and in astandard 9 within the reservoir and this shaft carries a pulley 10outside of the reservoir and a pinion 11 within the reservoir. Thepinion 11 meshes with a gear 12 arranged within the reservoir on a stubshaft 13 supported on the wall 7 of the reservoir. A disk 14 is fastenedto the gear 12 and is provided with a groove 15 and a collar 16. Apiston 17 is arranged to operate in the pump cylinder 18 supportedwithin the reservoir and this piston has on its u per end a rectangularframe 19 provided wit 1 inturned side flanges 20 which operate in thegroove 15 (Fig. 3). The disk 15 carries a wrist pin 21 which operateswithin a frame 21 on the lower end of a plunger 22, the latterprojecting upward through an opening 22 in the frame 19 and an opening22 in the reservoir and carrying a spring 23 which is confined betweenthe top of the frame 19 and nuts 24 on the outer end of the plunger. Thepump cylinder is provided with a tubular extension 25 at its lower endwhich has an inlet opening 26 normally closed by a ball valve end of theextension 25 and to a bore 31 which forms an oil distributing channel inthe casing 32 and communicates independentlywith each of the valvedfeeds. Each of these valved feeds comprises an upwardly inclined passage33 leading from the distribut ing channel 31 to the seat 34 of the valve35 carried by a regulating screw 35-, this seat being located at theupper end of a passage 36. The screw 35 operates in a boss 37 on which acap 38 is screwed. A plunger 39 is arranged in a chamber 40 in the valvecasing 32 below the passage 36 and this plunger is normally held in theposition shown in Fig. 5 by a spring 41 located between the end of theplunger and an adjusting screw 42 in one end of the chamber 40. Theplunger carries a rod 43 which projects through an opening 44 in thevalve casing and is provided with a handle 45 of any suitable character.The inner end of the plunger is provided with an angularly disposedchannel 46 which receives the oil from the passage 36, when the partsare in the position shown in Fig. 5 and permits it to flow therethroughinto the chamber 40 and thence to the ni ple 47 whence it is carried tothe parts to be lubricated. The plunger is also provided with a bleedergroove 48 which forms a communication, when the parts are in theposition-shown in Fig. 4 between the passage 36 and a passage 49 in thevalve casing below the chamber 40 and discharging through a sightchamber 50 and an opening 51 into the reservoir. The sight chamber islocated in the part which has been generally referred to as the valvecasing and beneath the plunger 39 and it is provided with a glass front52. It will be understood that all of the feeds are similarly rovidedwith the parts hereinbefore descri ed and illustrated in Figs. 4 and 5and that the apparatus may be equipped with as many of these feeds asdesired.

The operation may be briefly described as follows:Assuming first that itis desired to regulate the feed, the pump is started in operation andthe plunger 39 is pushed inward until the bleeder groove 48 is alinedwith the passages 36 and 49.- The oilwill flow through the pipe 30, thedistributing channel 31 into the passage 33 and passage 34 through thegroove 48 and passage 49 and drip through the sight chamber 50 andopening 51 back into the reservoir. By observing the drops through theglass 52 and adjusting the screw 35 the feed can be regulated asrequired and in this connection it will be observed that each feed isseparately regulated and therefore that the flow of oil in the severalfeeds may be the same or dill erent as desired. Then pressure on theplunger is released to permit the spring 41 to return the plunger to itsnormal position, as shown in Fig. 5, whereupon the oil flows frompassage 36 through channel 46 and chamber 40 to the feed nipple 47. Tooperate the pump power is applied to the shaft 8 whereby the gear 12 anddisk 14 are revolved. The wrist pin reciprocates the plunger 22 and thepressure of the spring 23 operates the piston 17. The

v'rist pin operating in the frame 21 reciprocates the plunger 22 and onthe upward stroke of the plunger the frame 21 engages the frame 19 toraise the piston 17. hen the wrist pin proceeds on its downward strokecarrying with it the plunger, the spring 22 is compressed by theresistance of the piston and by expansion operates the piston in adownward direction. The pump sucks in the oil from the reservoir throughopen ing 26, unseating ball valve 27, and forces the oil from thecylinder 18 into delivery )ipe 30 by unseating the ball valve 29, theball valve 27 being seated during the delivery stroke of the pump. Thesupply of oil delivered by the pump is regulated by spring 23 to avoidexceeding the amount of oil required because the spring will notoperatethe piston when theback pressure on the piston is greater than theexpansive pressure of the spring.

As the passages 33 leading from the distributing channel to the valveseats 34 are inclined upwardly the oil will be prevented from wastingwhen the pump is not in oper ation. The-nuts 24 on the plunger 22 can beadjusted as required to provide the proper pressure for operating thepump piston.
